That is, after the pipe / rod touches the limit switch, the control module 7 receives the signal and controls the feeding mechanism 10 to stop working. At the same time, the control module 7 controls the clamping cylinder 16 to lift the driven track wheel 19, and at the same time controls the pneumatic rotary chuck 9 to clamp the pipe / rod. After clamping, the driving motor drives the pneumatic rotary chuck 9 to rotate, and finally the cutting tool driving cylinder 33 indirectly drives the cutting tool to cut the pipe / rod. In order to avoid burrs remaining due to insufficient precision affecting the workpiece falling off, the pressing cylinder 5 can be controlled to press down on the cut material to assist in discharging.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
